Integrated telecommunications handset

ABSTRACT

A rugged, ergonomic integrated telecommunications handset includes an electronic controller that interoperates and controls the universal remote control (URC), which connects to multiple radios simultaneously. The controller downloads options which are implemented by the controller. The handset has an ability to vibrate in a silent mode, and has a memory capacity, as well as GPS capacity. Ergonomically, the handset has a pair of side arrays of protruding ribs, which enhance gripping, preventing the handset from falling out of the user&#39;s hands, even if the user has gloves on in inclement weather conditions in the field. While compatible with the latest radio system software defined dual net and dual channel radio equipment, the handset is also backward compatible with single radios or with two or more separate radios.

FIELD OF THE INVENTION

The present invention relates to a rugged, ergonomically-designedintegrated telecommunications handset for wireless and wirelineapplications with single or multiple radio or multiple channel radios ordual net/channel radio.

BACKGROUND OF THE INVENTION

A “‘two-way radio’” is a radio that can both transmit and receive, e.g.,a transceiver, unlike a broadcasting receiver which only receivescontent. Two-way radios are available in mobile radio, stationary orbase station radio and hand-held portable configurations. Hand-heldradios are often called walkie-talkies, and include “push-to-talk” or“press-to-transmit” buttons to activate the transmitter. Thesehalf-duplex communications devices generally are not configured tosupport simultaneous two-way communications. One or more mechanismstypically are implemented in half-duplex communications devices to helpensure that is in a transmit mode only at the appropriate times. Apush-to-talk (PTT) button places the communications device in a transmitmode while pressed or engaged and returns the communications device to areceive mode when the PTT button is released or disengaged. A voiceoperated (VOX) feature provides that a user's voice or other soundtriggers the communications device to enter a transmit mode.

The first truly mobile two-way radio was developed in Australia in 1923.In 1933, the Bayonne, N.J. police department successfully operated atwo-way system between a central fixed station and radio transceiversinstalled in police cars. This allowed for rapidly directing policeresponse in emergencies. During World War II, walkie talkies, or handheld transceivers were used extensively by air and ground troops.

Conventional radios operate on fixed RF channels. In the case of radioswith multiple channels, they operate on one channel at a time. Theproper channel is selected by a user. The user operates a channelselector or buttons on the radio control panel to pick the channel. Inmulti-channel systems, channels are used for separate purposes. Achannel may be reserved for a specific function or for a geographicarea. Motorola uses the term “mode” to refer to channels on someconventional two-way radio models. In this use, a mode consists of aradio frequency channel and all channel-dependent options such asselective calling.

The use of two-way radios significantly improved communications andtherefore effectiveness of military actions during and after WWII. TheSCR 300 is the two-way radio or walkie talkie used by US forces towardsthe end of war. The SCR 300 comprised a backpack unit and a handsetconnected to the backpack, and weighed 30-40 pounds. Motorola (GalvinManufacturing) developed the first hand-held two-way radios shortlythereafter (SCR 536), were became available at the platoon and squadlevel.

Various handsets have developed for use with two-way radios for militaryapplications, for example, H-207/VCR, H-189/GR, H-250. The H-189 handsetis a rugged repairable handset unit molded out of polycarbonate lexanthat utilizes a 1000 Ohm earphone element, a 150 Ohm dynamic noisecancelling microphone, a PTT switch and 6 foot retractile cordterminating in a 5-pin audio connector. The handset is configured to beinterchangeable with H-250 Handset, and is intended for use withmilitary man-pack radio equipment such as AN/PRC-70 and AN/PRC-77.

While such known radio handsets are quite effective for intendedmilitary applications, they are not without shortcomings. Suchconventional radio handsets are physically cumbersome, and areconstructed with limited operational electronics capabilities.

SUMMARY OF THE INVENTION

It is an object of this invention to provide a rugged, ergonomicintegrated telecommunications handset, which overcomes the shortcomingsof the conventional arts.

The lower portion isfolded against the upper portion; the keyboard and the visual displayare covered, leaving the earpiece uncovered. When integral, the onepiece handset is an integral handset formed of a single piece, with anearpiece at one upper portion thereof and a mouthpiece at a lowerportion thereof.

In another embodiment, the handset is a radio handset with a number offeatures which by selection for inclusion or exclusion creates the basisfor five distinct handsets, where each of the headsets are designed toserve the different requirements. The general design of the housing withkey dimensions, placement of feature controls, and functionalattachments offers superior ergonomics for the warfighter, in all of thehandset variations. While compatible with the latest Joint TacticalRadio Systems software defined dual net equipment (such as the HarrisFalcon Radio AN/PRC-155), the inventive Radio handset also is backwardcompatible with single radios (H-250 replacement), with two separateradios (each H-250 replacements), with a field phone (H-350replacement), and with a Dual Net radio.

This is advantageous in view of the fact that the handsets of thepresent invention frequently are used with different radios that handletheir multiple channels in different ways. Some of the radios used withthe inventive handsets sum all the channels together before sending themto ancillaries, while others send a separate audio signal for eachchannel. Also, depending on the manufacturer and radio, multiplechannels have different designations such as “channel”, “net”, “talkgroup”, etc. The inventive handsets are available in severalconfigurations: multi-channel, multi-radio and dual net/channel radio.The multi-channel handset ancillaries are designed to be used withmulti-channel radios, but the exact wiring is dependent upon theconfiguration of the radio. The multi-radio handset ancillaries of thepresent invention are designed to be used with more than one radio, witheach radio having a standard wiring configuration.

The handsets used in the multi-channel mode are used in different ways.The handset can be connected to the radios directly, or to theloudspeaker, but never to a full headset or a microphone set (although auser can connect a listen-only headset to the handset). The Push to Talk(PTT) controller is meant to be used in-line with headsets and otherproducts that do not inherently operate multiple channels, thusenhancing their capability. The microphone set is used in much of thesame way as the handset, except that it cannot receive audio.

By the term “standard radio” the handset is meant to include a Ground,an Audio, one PTT button and a microphone.

By the term “dual net radio” the handset is meant to include a Ground,an Audio, a first PTT button, a microphone and a second PTT button. Adual Net radio is a single radio that is capable of operating twochannels, or “nets”, at the same time.

These two PTT buttons operate two independent nets via hard wiring.

In an embodiment with a “dual radio” loudspeaker, the loudspeaker iscapable of receiving and transmitting audio signals from two independentradios. The conventional scrambling is done by the radio.

In the two-radio embodiment, there is a wired Y connection. The otherembodiments are for the dual NET radios which are already set up with amating connector for the radio handsets. The handset without a wired Yconnection is used with a dual Net radio.

In another embodiment, the handset is used with a field phone. A fieldphone is a hard-wired phone system usually found in larger vehicles suchas tanks and APCs. They usually require a “hot mic”, or a dedicated pairof connector pins that are always hooked up to the microphone,regardless of PTT status.

Functionally, a conventional thumb wheel is provided on the handsets, ina novel visual and ergonomic design, as it is positioned so that one canoperate it from the front of the handset or from the side (when thehandset is held against one's face). In most variations of the handset,this thumbwheel will increase or decrease the volume of audio heardthrough the earphone or listen-only headset. In the Dual Radio variationof the handset (Y-branch), this thumbwheel acts as a volume balancecontrol between the two radios.

That is, mouthpiece portion (28′) is not foldable. Whilehandle (10″) is rigid, and therefore larger in length than handsets (10;10′) when in their folded/closed positions, the rigid fixed length isbeneficial in its ability to be reliably affixed to a helmet arranged toreceive it (helmet not shown).

The FIG. 18B view highlights one definition of an angle at whichmouthpiece portion (28′) extends from an axial center of the mainhousing of handset (10″). FIG. 18C is a perspective view of a wirelineembodiment of handset (10″), including wire (58), which handset (10″)may also be configured for wireless operation.

FIG. 19 is a block diagram depicting one embodiment of an integratedelectronics system (100), which may be included in the integratedtelecommunications handsets of the invention. The integrated electronicssystem (100) enables the handset to connect to multiple radiossimultaneously; to function with voice activation capability; tofunction as a speaker microphone; to function as a data/video uploaddownload interface to radio for transmission to the network; to operatea standard 12-button keypad and operate an active display, i.e.,accepting touch user inputs in some models. The optional electronicsprovides wireless radio interface, and wireless telecommunicationsability (GSM capable). Preferably, the radio option includes a URCcapability, operating with a Zigbee or other platform format. For thatmatter, the electronics enable the handset to automatically match radioinput impedances, and receive multiple download configurations. Thehandset electronics will operate with an interface port for in-eardevices, DTMF tone generation, silent mode notification (vibration),automatic gain control, IP based functionality.

The physical speaker capability is dynamic or balanced armature. Theergonomic design enables use with gloved hands. For that matter, thehandsets weigh less than 1 lb. with cable, as wholly user (field)configurable, disposable and may be produced in any color options indurable polycarbonate. For that matter, the handsets are Mil-STD-810tested and certified; EMI/EMP hardened, and can by GPS enabled forlocation/position verification. Preferably, each includes up to 1gigabyte embedded user memory, and operates with a small electronicsignal footprint to facilitate squad level communications when used formilitary purposes. A versatile phase-locked loop in the optionalelectronics allows the device to operate at various frequencies, up toand exceeding GSM. The handset is waterproof to 3 meters (for a limitedtime) and includes emergency call tone generation for situation wheretalking is not an option. For that matter, the handset can be TEMPESTcertified with radio systems.

The heart of the electronic operation is the programmablemicrocontroller (110). The invention, however, is not limited to aprogrammable microcontroller per se, but may be controlled by discreteelectronics and/or a microprocessor. When controlled by amicroprocessor, the microprocessor is operated in accordance with a setof computer readable instructions (e.g., a software application)instructions that operates/implements each of the following features incooperation hardware elements.

That is, the microprocessor or programmable microcontroller (110)control(s) responses to a number of various inputs functions (111).Input functions (111) include voice activation (VOX) hardware (112),receives and processes data from serial (I/O) port (114), Optionalkeypad function (116), and push-to-talk (PTT) function (118). Theoptional keypad function cooperates with DTMF encoder/decoder and A/Dconversion function (120), which cooperates with GPS functionality(122). The push-to-talk (PTT) function cooperates with microphone (124),filters and AGC (128). In the case of a microprocessor, themicroprocessor operates by a set of computer readable instructionscomprising a handset operational application program. In a case of anembedded control system or a memory programmable controller (discussedbelow in more detail), the functional element hardware is directlyconnected to the embedded control system or memory programmablecontroller in order that it may respond without delay normallyassociated with a microprocessor driven application programs.

Cellular electronics (132) cooperates with programmable microcontroller(110), keypad (116) and DTMF function (120), driving vibration function(134) as part of the integrated electronics system (100). As indicatedin FIG. 19, various drivers may be included to implement the actualmicrocontroller control. LCD display (136) is shown to be controlled(driven) via microcontroller (110), which presents display imagescomprising GPS, channel positioning, audio elements such as volume leveland text messages/messaging control modes (represented by block (138)).Encryption function (140) provides for the encryption of video, voiceand other data exchanged between the microcontroller (110) and awireless interface (142) and an impedance matching/voltage biasingfunction/device, for handset wireline functioning.

A user audio function (146) outputs audio to received audio channels,including streaming audio. The audio data is provided to/fromtransceiver (152). The audio may be sampled and provided to a listeningdevice by in-ear function (150). All functions, while described foroperation in one direction, are operation in both directions. Thehardware elements that may comprise/cooperate with the identifiedfunctions discrete or monolithic. Preferably, the system is integratedon a single board, or a single ASIC.

According to the invention, many of the functions controlled by theintegrated electronics system are time critical, in view of the factthat every second counts for users of the handset under combatconditions. In view of same, the programmable microcontroller 110 ispreferably an embedded control system or a memory programmablecontroller, known for use in providing and controlling time-criticalfunctions. A memory programmable controller is an electronic controllerutilized to implement very specific and time critical operations. Thememory programmable controller has input and output interfaces directlyconnected to the hardware elements and components above-described, andshown in FIG. 19. The controller is programmed specifically to controlthe input data of the time-critical functions.

Alternatively, the programmable microcontroller 110 may be an embeddedcomputer system that is driven by firmware include in a ROM (read-onlymemory) located as part or connected directly to programmable controller110, e.g., a flash ROM. Such an embedded controller system will alsohave RAM (random access memory), e.g., as static RAM. In comparison toconventional computer systems found in conventional handsets, embeddedsystems more quickly and efficiently process time-critical applications.
